How We Value Your Ruby
The 4 Factors That Determine a Ruby’s Value
Fine rubies are among the most valuable gemstones on Earth — exceptional stones routinely exceed diamonds in per-carat price. Our gemologists assess all four critical factors transparently in front of you.
Color The defining factor. The ideal is a pure, vivid red sometimes described as “pigeon’s blood” — a saturated red with a slight blue modifier and no brown or orange tones. Color drives the majority of value in fine rubies.
Origin Burma (Myanmar) produces the world’s most prized rubies. A Burmese origin certificate from GIA, GRS, or Gübelin can multiply value 3–10x over comparable stones from other origins. Mozambique and Thailand also produce significant stones.
Heat Treatment The vast majority of rubies are heat-treated to improve color and clarity. “No heat” or “unheated” rubies of fine color command extraordinary premiums — often 5–20x the price of a heated equivalent. Treatment status is assessed using standard gemological testing.
Clarity & Carat Rubies typically contain more inclusions than diamonds. Eye-clean stones are rare and command premiums. Carat weight increases value non-linearly — fine rubies above 3ct are exceptionally rare and exponentially more valuable per carat.
Origin Matters
Where Your Ruby Comes From Determines Its Value
Burmese rubies are the gold standard — a fine unheated Burmese ruby can be worth more per carat than a comparable diamond. Origin is verified by lab report.
🇲🇲 Burma (Myanmar) The Mogok Valley has produced the world’s finest rubies for centuries. True “pigeon’s blood” color is almost exclusively Burmese. GIA or GRS-certified Burmese origin commands the highest premiums of any colored stone in the world. Highest Premium
🇲🇿 Mozambique Mozambique’s Montepuez mine has become one of the world’s most significant ruby sources since its discovery in 2009. These stones can approach Burmese quality in color and are increasingly recognized by major auction houses. High Premium
🇹🇭 Thailand & Other Thailand, Sri Lanka, and Madagascar also produce rubies. Thai stones tend toward darker, more brownish red. Stones from these origins are valued on their own merits and can still be significant depending on color and size. Good Value

Our Expertise
Colored Stone Specialists in the Diamond District
Fine rubies are among the rarest and most valuable objects in the gemstone world. A fine unheated Burmese ruby of 3 carats or more can sell at major auction houses for hundreds of thousands of dollars per carat — exceeding comparable diamonds by a significant margin. Evaluating them correctly requires specialized knowledge that most general buyers simply don’t have.
At Buyers of New York, our GIA-trained gemologists have decades of experience in colored stone evaluation. We assess rubies using spectroscopic analysis, UV fluorescence, and microscopic inclusion examination to identify origin characteristics and treatment status. We reference recent auction results from Christie’s, Sotheby’s, and Bonhams for significant certified stones.
We are transparent about every factor in our evaluation. You see exactly what we’re seeing, understand why your stone is valued as it is, and receive a fair offer based on today’s actual market — not a fixed price list.

“I had a ruby ring I inherited and had no idea if it was worth anything. The gemologist identified it as a Burmese stone with minor heat treatment and gave me an offer that was far above what I expected. They explained everything clearly and paid cash on the spot. Incredible experience.”

The Ruby Selling Guide
What You Need to Know Before Selling a Ruby in NYC
Fine rubies are among the rarest and most valuable gemstones in the world. The most exceptional pieces — unheated Burmese rubies of vivid pigeon’s blood color and significant carat weight — routinely surpass diamonds at major auction houses in per-carat price. Understanding what drives ruby value is essential before selling.
What Is “Pigeon’s Blood” Color?
Pigeon’s blood is the trade term for the most prized ruby color: a pure, vivid red with a slight blue modifier and strong fluorescence, showing neither orange nor brown tones. The term originated with Burmese rubies from the Mogok Valley. GRS (Gemmological Research Switzerland) is the lab most associated with the official pigeon’s blood designation on lab reports, which can dramatically increase a stone’s value.
Why Does Heat Treatment Matter So Much?
Over 95% of rubies on the market have been heat-treated to improve color and clarity. This is widely accepted in the trade. However, “no heat” rubies of fine color are extraordinarily rare — perhaps 1-2% of the market — and command premiums of 5–20x or more over treated equivalents of the same color grade. A lab report from GIA, GRS, or Gübelin confirming “no indications of heating” is one of the most value-adding documents in colored stones.
How Do Ruby Prices Compare to Diamonds?
For exceptional quality, fine rubies significantly exceed diamonds in per-carat price. A flawless D-color diamond might sell for $15,000–$25,000 per carat at auction. A fine unheated Burmese ruby of pigeon’s blood color in the same weight can sell for $100,000–$1,000,000+ per carat. The most exceptional rubies ever sold include the Sunrise Ruby (Burmese, 25.59ct, unheated) which sold at Sotheby’s Geneva for over $30 million.
What Is the Difference Between a Ruby and a Pink Sapphire?
Both ruby and pink sapphire are the mineral corundum — the only difference is color. The dividing line between ruby and pink sapphire is contested and varies by country and trade convention. In the US, the GIA defines ruby as red corundum with saturation above a certain threshold. Stones below that threshold are classified as pink sapphire. The distinction matters commercially — “ruby” commands higher prices than “pink sapphire” of comparable quality. We identify the correct classification and price accordingly.
FAQ
Common Questions About Selling Rubies in NYC
We examine characteristic inclusion patterns, spectroscopic signatures, and UV fluorescence that indicate Burmese origin. For significant stones, we recommend GIA, GRS, or Gübelin origin certification which provides definitive documentation and increases value significantly.
Enormously for significant rubies. A certificate confirming Burmese origin and “no indications of heating” can multiply your stone’s value 5–20x over an uncertified equivalent. If you have one, bring it.
We use UV fluorescence testing, spectroscopic analysis, and microscopic examination of inclusion integrity to assess heat treatment. Heated rubies show altered inclusions and specific spectral signatures that distinguish them from unheated stones.
Same day. Accept the offer and receive cash immediately. Most evaluations complete in 15 minutes. Very significant or complex stones may require additional assessment time.
Yes. We assess the ruby and metal setting separately and pay for both. Designer signed pieces from Cartier, Bvlgari, Van Cleef & Arpels carry premiums above stone value that we identify and pay.
